SN74LV4051APW Description

The SN74LV4051APW from Texas Instruments is a high-performance, 8:1 analog multiplexer/demultiplexer designed for low-voltage applications. Housed in a 16-pin TSSOP package, this IC features an on-state resistance (Ron) of just 75Ω (max) and operates over a wide supply voltage range of 2V to 5.5V, making it suitable for mixed-voltage systems. With a -3dB bandwidth of 35MHz and fast switching times (14ns Ton/Toff), it ensures minimal signal distortion in high-speed applications. The device exhibits ultra-low leakage current (100nA max) and low channel capacitance (0.5pF CS(off), 23.4pF CD(off)), enhancing signal integrity. Its 1.3Ω channel-to-channel matching ensures consistent performance across all channels.
